Summary:
This has been replaced by the NVPTXInferAddressSpaces pass. We've had
the new one as the default with the old one accessible via a flag for
some months now, and we've had no problems.

Summary:
The old address space inference pass (NVPTXFavorNonGenericAddrSpaces) is unable
to convert the address space of a pointer induction variable. This patch adds a
new pass called NVPTXInferAddressSpaces that overcomes that limitation using a
fixed-point data-flow analysis (see the file header comments for details).
The new pass is experimental and not enabled by default. Users can turn
it on by setting the -nvptx-use-infer-addrspace flag of llc.

Apparently, the style needs to be agreed upon first.

Summary:
We used to assume V->RAUW only modifies the operand list of V's user.
However, if V and V's user are Constants, RAUW may replace and invalidate V's
user entirely.
This patch fixes the above issue by letting the caller replace the
operand instead of calling RAUW on Constants.
Test Plan: @nested_const_expr and @rauw in access-non-generic.ll

Summary:
This patch allows NVPTXFavorNonGenericAddrSpaces to remove addrspacecast
from longer chains consisting of GEPs and BitCasts. For example, it can
now optimize
%0 = addrspacecast [10 x float] addrspace(3)* @a to [10 x float]*
%1 = gep [10 x float]* %0, i64 0, i64 %i
%2 = bitcast float* %1 to i32*
%3 = load i32* %2 ; emits ld.u32
to
%0 = gep [10 x float] addrspace(3)* @a, i64 0, i64 %i
%1 = bitcast float addrspace(3)* %0 to i32 addrspace(3)*
%3 = load i32 addrspace(3)* %1 ; emits ld.shared.f32
Test Plan: @ld_int_from_global_float in access-non-generic.ll

Require the pointee type to be passed explicitly and assert that it is
correct. For now it's possible to pass nullptr here (and I've done so in
a few places in this patch) but eventually that will be disallowed once
all clients have been updated or removed. It'll be a long road to get
all the way there... but if you have the cahnce to update your callers
to pass the type explicitly without depending on a pointer's element
type, that would be a good thing to do soon and a necessary thing to do
eventually.

Removes unnecessary casts from non-generic address spaces to the generic address
space for certain code patterns.
